Southern Russia has potential to further develop aquaculture with new production technologies and new species like catfish, pike-perch, tilapia and sturgeon. 

The recent 2017 Aquaculture Innovation Workshop in Vancouver brought together numerous stakeholders involved in and interested in fish farming – particularly salmonids – in the growing industry of closed-containment systems. 

Caviar, or lightly salted sturgeon roe, has been enjoyed for centuries as an expensive gourmet delicacy. After a drastic decline in wild sturgeon stocks, aquaculture stepped in to fill the void. But can farmed supply find lasting balance with market demand? 

Aquaculture of high-value white sturgeon is in its early phases in British Columbia, Canada. 
Given the long time required to produce caviar, licensed producers are looking at developing markets for value-added products and byproducts based on sturgeon meat. 

The Fishery is an inland farm in California that raises largemouth bass, carp, sturgeon and catfish in a recirculating system that minimizes water use. 

Research with sturgeon and carp species indicated that encapsulated artemia has high potential to carry probiotics or other beneficial microorganisms. 

Biopsies and polarization index measurements of mature sturgeons are highly variable and not always accurate in indicating egg maturity. Ultrasonic imaging offers a simple, less time-consuming and reliable alternative for evaluating sturgeons’ sex and oocyte maturity. 

Fish farms in Armenia have developed a diversified product base that includes value-added, ready-to-eat foods for export, as well as live and processed fish for domestic markets.
